Experience

Wisutech (Auto Machine Learning Startup), Beijing, China, data engineer Mar. 2019– Jun 2019

• Built a big data platform based on Hadoop and Spark including 4 nodes to solve Terabyte data .

• Communicated with clients to decide the feature extracting process based on the business logic.

• Conducted exploratory data analysis(EDA),including assessing the quality of data, visualizing the distribution of variables with pandas, and assessing the correlationship of features.

• Used Spark, Hadoop and Shell to implement feature engineering including missing value population, one-hot encoding,removing redundant feature, extraction from timestamp data and data normalization.

• Built models(GBDT) for loan company clients to make decisions on loan applications. Built model(LR) for oil company clients to make prediction of oil sales.

• Evaluated the performance of the models with precision, recall and confusion matrix. Improved the performance of model by extracting better features.

Project

Research: Using Quantum Computing to solve graph isomorphic problem, University of South California,research assistant. Jun. 2018– Present

• Contributed to propose to solve graph isomorphic problem (classic computer science problem) using a new quantum annealing technique.

• Used python to interact with quantum computer (D-wave:first commercial quantum annealer).

• Successfully demonstrated the feasibility of use quantum annealing to distinguish graphs and prepared a draft to report this result

Research: Optimization performance for sensors based on ML, Beijing University of Posts and Telecommunications, research assistant. Jun. 2017-Jun.2018

• Contributed to construct a 7 layers neural network to predict the structure parameter that can produce the optimized transmission spectrum.

• Wrote code to gather examples uniformly from a transmission spectrum.

• Tuned the hyper parameter including learning rate and activation function, finally achieved 0.8729 precision on test sets.

Project: Built a Class Registration System Sep. 2019-Present

• Built a web application providing class registration based on spring MVC .

• Designed a front end interface with HTML and CSS based on Angular.

• Used Hibernate to provide better database operations . Publications
